You mean IRRE relation from one record to another record of the same table?
Or did you really mean "itself"? ;-)

The first thing is exactly how it is done in the ICE pack.
It's linking tt_content records to other tt_content records which can even
be nested.
The only thing you have to make sure is, that none of the records that are
already selected as a child can be used as parent of their parent and vice
versa. This is just to avoid loops and can easily be done with an
itemsProcFunc setup in ext_tables.php

You can see it in the ICE box, which is using
tx_icebox_tca_mods->remove_from_parents for it.
